Hi Rina

I here summarize the private discussion we've already had

one possibility is to have an option for gengetopt (say, --failsafe) 
that generates a parser that does not exit or report an error in case an 
option is not recognized and the parts not recognized can be put in a 
field for later processing

the other one, is to let the options for a plugin to be the argument of 
an option of the main program; there's a section in the manual of 
gengetopt to deal with such a situation: 
http://www.gnu.org/software/gengetopt/gengetopt.html#String-Parsers-and-Multiple-Parsers

however, the --failsafe option (probably it's not the best choice for a 
name) would be interesting anyhow, so I'll probably add this 
functionality too.

hope to hear from you soon
cheers
